FAQ:
Why imported Composite Manhole cover/Grating fromChina?
1. Very competitive price, it will save you third or even half cost;
2.Good quality, don't worry much about the quality, actually, most of the building materials you buy from Miami, Dubai ,Italy, South Africa or your local market are imported from China. So why not buy direct from China. The key point is to find a reliable supplier who is honest and professional to take care of the quality and delivery time.
3.Chinahas full range of Manhole covers which Follow En124 for your market, like A15,B125,C250,D400.
- Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
- The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine, according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
- Q:When there is no flaw detection for large casting parts, is there any crack inside?
- According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
- Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.
- Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?
- For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.
- Q:In the design of casting steps and precautions, for casting design, we have what experience?.
- A: in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
- Q:What is the difference between casting and stamping parts?
- Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.
- Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
- The aim is to make the grain fine and distribute the carbide evenly. The difference between normalizing and annealing is that normalizing cooling rate is slightly faster than annealing cooling rate, so normalizing structure is finer than annealing structure, and its mechanical properties are also improved. In addition, normalizing furnace cooling does not occupy equipment and has higher productivity. Therefore, normalizing may be used instead of annealing as much as possible. The main application areas of normalizing are as follows: for low carbon steel, after normalizing, the hardness is slightly higher than that of annealing, and the toughness is better. It can be used as the pretreatment of cutting. Used for medium carbon steel, instead of quenching and tempering, as the final heat treatment, or as an induction heating method before surface hardening. Used for tool steel, bearing steel, carburizing steel, etc., it can eliminate or restrain the formation of network carbide, so as to obtain the good organization of spheroidizing annealing. For cast steel, the microstructure can be refined and the machinability can be improved. Used for large forgings, which can be used as final heat treatment, so as to avoid larger cracking tendency during quenching.
- Q:What should I pay attention to when designing a casting structure?
- (2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
- Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
- Q:Why does the surface of stainless steel casting mirror mirror ripple?
- Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.
